It's nice to meet you, Elad. I talk to myself all the time. It's when the voice starts getting aggressive that it's a problem. It's one thing to discuss something out loud, like Mike said, "weigh the pros and cons". It's another thing to have the voice tell me to F*** off or to shut up, stuff I would never say to anyone. Then it's time to figure out what that other voice's purpose is. It sounds like you're just having normal conversations, though. I think that's pretty normal.
Post anytime, but don't feel like you have to. Your support is enough.
